WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: The World Health Organization (WHO) has reported a total of 48 cases by October 15, 2021. The continuous genomic reassortments of H5N6 and other subtype avian influenza viruses (AIVs) pose a long-term threat to public health and the poultry industry.
Three new cases of H5N6 that occurred from January to September 2021 in Chongqing Municipality, China were reported in this study. Epidemiological information of the three cases showed raising poultry and visiting live poultry market contributed to these infections, and there was no evidence of human-to-human transmission of H5N6 currently but a potential spatial cluster. An increase of H5N6 cases was recorded in the area.
WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: In case of unexplained pneumonia or severe respiratory infection, the patients' epidemiological history of contact with poultry or live poultry markets (LPMs) may be an important interrogation to help diagnose. Extensive and long-term surveillance of avian influenza viruses in LPMs is essential.
关于该主题已知的信息有哪些？：世界卫生组织（WHO）报告称，截至2021年10月15日，共有48例病例。H5N6及其他亚型禽流感病毒（AIV）的持续基因组重配给公共卫生和家禽业带来长期威胁。
本研究报告了2021年1月至9月在中国重庆市发生的3例新的H5N6病例。这3例病例的流行病学信息显示，饲养家禽和到访活禽市场是这些感染的原因，目前没有证据表明H5N6存在人传人情况，但存在潜在的空间聚集现象。该地区记录到H5N6病例有所增加。
对公共卫生实践有何启示？：对于不明原因的肺炎或严重呼吸道感染病例，询问患者与家禽或活禽市场（LPM）的接触流行病学史可能是有助于诊断的重要问诊内容。对活禽市场的禽流感病毒进行广泛和长期监测至关重要。
